A typical vertebra is composed of the following three elements:
Spina bifida (spina bifida) is a complex birth defect in which there is incomplete development of the laminae of the vertebral arch. If only the vertebral lamina is undeveloped and the spinal cord is intact without any skin abnormalities, this malformation is called spina bifida occulta and it occurs in 5% of the population. Most clinical cases of vertebral lamina defects are concurrent with meningeal defects and are called meningocoele which is a prolapse of the meninges. If the spinal cord and meninges are prolapsed it is called meningomyelocoele. The presence of this neurological defect after birth requires urgent neurosurgical intervention.
